TYPE-WRITER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 605,373, dated June '7, 1898. Application filed February 4, 1895. Serial No. 587,156. (No model.)

and it consists in a foot lift or treadle connected with the shifting lever or bar, as hereinafter described, or other mechanical device, which foot-lever is so arranged as to be operated by an upward motion of the front part of the foot, to shift the platen.

I will now describe my invention so that others skilled in the art to which it apperend of which is adjustably secured the lift tains may manufacture and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of my improvement as applied to'a type-writer. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged view of the lift or treadle and supporting attachment, partly in section. Fig. 4 is a planview of a portion of the platen-shifting key-lever, and, Fig. 5 is an elevation of my improvement applied to a type-writer stand or desk.

Like symbols of reference indicate like parts wherever they occur.

In the drawings, 2 represents the platenshifting lever, having the usual finger-key 3. Secured to the frame 4 of the type-writer is a rod or supporting-standard 5, to the lower or treadle support 6, which is provided with a socket which fits on the lower end of the rod 5 and is adjustably secured by the set-screw 7 to regulate the length of the standard and the position of the treadle. On the lower end of the support 6 is shown a rubber block 8, which rests on the floor. Pivoted to the sup port 6 is the foot-treadle 9, which is raised from the floor sufficiently to allow the foot of the operator to pass beneath the forward part of the lift or treadle, so that the treadle may be operated by lifting the forward part of the foot, as is indicated by the dotted lines in Fig. 2. Suitably attached to the rear end of the treadle 9 is the rod 10, the other end of which is connected to the platen-shifting 1ever 2.

Then the operator desires to shift the platen to print capital letters or for any other purpose, all that is necessary is to slightly raise the toes of the foot under the lift or treadle, which moves the platen-shifting 1ever 2 and shifts the platen without the use of the hands.

In Fig. 5 I show a modification in which the treadle-supporting standard 5 is secured to the type-writer desk instead of to the typewriter frame, and a turnbuckle is shown on the rod 10. This turnbuckle is preferably employed in all cases where the rod 10 is used. Other modifications will suggest themselves to those skilled in the artas, for instance, the treadle may be pivoted to a support secured to the floor or a chain may be substituted for the rod 10.

My invention may be applied to all typewriters having a shifting-platen or shiftingtype system.

The advantages of my invention will be appreciated by those who use the same. Owing to the treadle being operated by a lifting movement the foot of the operator may remain at rest under the treadle until it is necessary to shift the platen,which shifting may be quickly accomplished by the upward motion of the forward part of the foot.

I claim as my invention 1. In a platen-shifting attachment for typewriters, the combination with a shifting mechanism, of a foot -lever arranged to receive the toe portion of the foot beneath it and to shift the platen by an upward lift.

2. The combination with a shifting device for a type-writer, of a foot-lever arranged to receive the forward part of the foot beneath its projecting end, the other end of the lever said lever, and a connection between the lever having a direct link connection to the shiftand the shifting device. IO ing device so that an upward lift of the foot In testimony whereof Ihave hereunto set my will shift the platen. hand.

3. The combination With a shifting device FREDERICK G. BARBER. for a type-Writer, of a foot-lever arranged to Witnesses: receive the toe portion of the foot beneath its W. B. CORWIN, projecting end, an adj nstable fulcrum for JAMES K. BAKEWELL.
